My Plants Are Drooped...maybe Flowering??

i think i may have went into the flowering stage to early.....
my plants are healthy when the light is on for 12 hours
but when i turn them off and open my box up(of course in the dark)
they stop all droop down=(
i have clones i bought there over 2 weeks old now
and are pretty big..
opinions would be so appreciated!

THANK YOU EVERYONE FOR THE HELP THATS OFFERED HERE!

You should have waited to change the photo cycle. The clones should have lived through it but it will not be strong enough to hold the weight of the buds.

do you think i should put the
MHL bulb back in????

mayb it gets 2 cold at night and ur plants droop

it could be that......
but what do you think on maybe i
put it into flowering to early??
would pics help??
